In a computer, when the data packet is transmitted from one network to another network, it is required to choose the best path for transmitting the packet. Hence, routing is the concept of the network layer of the OSI suite, which selects the best path for transmitting packets among the network. The router is a ...
Network Layer is responsible for how a machine in a network can communicate with a machine in a different network. The primary goal of this layer is to deliver packets from a source to a destination. The network layer splits data into fragments(data packets) and sends these fragments, which are then combined once the processing ...
Until the introduction of software-defined networking (SDN), a class of technologies that separates the network control plane from the forwarding plane to enable more automated provisioning and policy-based administration of network resources, hardware ruled the networking industry. The most accurate definition of SDN is the technology that separates the management of network devices’ control planes from the underlying data ...
OSI (Open System Interconnection) model is a conceptual model that is used to describe seven layers that computer systems use to communicate over a network. This model has been described in the form of 7 layers namely, Physical layer, Network layer, Data Link layer, transport layer, session layer, presentation layer and the application layer. All these 7 layers work together to transmit the ...
Data Link Layer is responsible for reliable point-to-point data transfer over a physical medium. To implement this data link layer provides three functions : What is Flow Control in the Data Link Layer? Flow control is a set of procedures that restrict the amount of data a sender should send before it waits for some acknowledgment from the ...
Cryptography is a term used in data communication that refers to protecting the private information shared between two parties. Network Security refers to securing and protecting the network and data to ensure the confidentiality of data. What is Cryptography? Cryptography generally deals with the study and practice of techniques for ensuring secure communication between two parties ...
If you are reading this article, you are most likely connected to the internet and viewing it at the Scaler Topics. Likely, you are currently utilizing Network Address Translation (NAT). More people now use the internet than ever anticipated, leading to the situation where the number of unique IP addresses provided by the IPv4, i.e.i.e.,232232 or 4,294,967,2964,294,967,296, is not enough. Network ...
Voice over Internet Protocol(VoIP) is a way of transmitting voice and multimedia over a network. VoIP enables users to place voice calls via their computer, smartphone, other mobile devices, dedicated VoIP phones, and WebRTC-capable browsers. VoIP is a technology that benefits consumers and businesses because it typically includes features not available on traditional phone services. ...
When the IP system was first introduced, finding a network and sending data to it was easier because the number of users on the internet was limited. As the number of users on the internet is increasing, sending a data packet to the computer you want in a network is becoming quite difficult these days. When a ...
Hubs and switches, both integral to networking, differ significantly in how they manage data traffic. Hubs simply broadcast data to all connected devices, leading to potential network congestion and inefficiency. In contrast, switches are smarter, forwarding data only to the specific device it’s intended for, improving network speed, and reducing unnecessary traffic. This fundamental difference ...
